摘要：The aim of this paper is to propose a control method for a doubly-fed induction generator used in windenergy conversion systems. The proposed control algorithm is applied to a doubly fed induction generator (DFIG)whose stator is directly connected to the grid and the rotor is connected to the grid through a back-to-back AC-DC-ACPWM converters. The control of the rotor-side converter is realized by stator flux oriented control and the fuzzycontroller performs robust speed control. The grid side converter (GSC) is controlled in such a way to guarantee asmooth DC voltage and ensure sinusoidal current in the grid side. The results obtained from a system using theproposed fuzzy controller show more accurate control performance and faster dynamic response with almost no steadystate error when compared to a system using conventional PI controller.
